Definitions
- the invention relates to a method for controlling and regulating a
- a rail pressure control loop comprises a reference junction for determining a control deviation, a pressure regulator for calculating a control signal, the controlled system and a
- Control deviation is calculated from the difference between nominal and actual rail pressure.
- the controlled system includes the pressure actuator, the rail and the injectors for
- a common rail system with pressure control in which the pressure regulator accesses via the control signal to a suction throttle.
- the suction throttle is controlled in negative logic, that is, it is fully open at a current value of zero amperes.
- a passive pressure relief valve is provided. If the rail pressure exceeds a critical value, for example 2400 bar, the pressure relief valve opens. The fuel is then discharged from the rail into the fuel tank via the opened pressure relief valve.
- Pressure relief valve adjusts itself in the rail a pressure level, which of the Injection quantity and the engine speed depends. At idle, this pressure level is about 900 bar, while at full load it is about 700 bar.
- the invention Based on a common rail system with a passive pressure relief valve and an independent rail pressure control on both the A-side and the B-side, the invention has for its object to ensure safe operation of the engine after failure of the rail pressure sensor.
- the method consists in that the rail pressure is further regulated, which can be sensed error-free, while the no longer detectable rail pressure in
- Rail pressure is controlled while the B-side rail pressure is still regulated.
- the B-side rail pressure sensor is defective, it is changed to a B-side emergency operation in which the B-side rail pressure is controlled while the A-side rail pressure is further controlled. If a double fault is detected, ie both rail pressure sensors are defective, the A side and the B side emergency operation will be activated
- Pressure relief valve then sets a rail pressure in the range of 700 bar (full load) to 900 bar (idle) in the A-side rail.
- B-side emergency operation is proceeded in an analogous manner. Safe engine operation is thus achieved by setting a defined state via the deliberately induced opening of the pressure-limiting valve. Since, in the case of a single fault, the rail pressure of the faultless rail is still regulated, this is operated at the best possible emission values and permits the further operation of the internal combustion engine with comparatively high power. In the case of a double fault, the internal combustion engine can continue to be operated with reduced power output.
- low-pressure-side suction throttle is acted upon as a pressure actuator in the opening direction.
- a desired current or a PWM signal as the drive signal of the intake throttle to a corresponding Not sunnyswert.
- a normally open suction throttle for example, zero amps is set as the emergency operating current value.
- An opening of the passive pressure relief valve can also be achieved if an emergency operating current value greater than zero is set, for. B. 0.4 amps. As a result, the heating of the fuel can be reduced.
- the energization duration of the injectors is calculated via an injector map as a function of a desired injection quantity and the respective actual rail pressure. If an A-side injector is to be activated, this is the A-side actual rail pressure. If a B-side injector is to be controlled, this is the B-side actual rail pressure.
- a defective rail pressure sensor therefore causes a faulty energizing time.
- the invention now provides that in the A-side emergency operation, instead of the A-side actual rail pressure, a rail pressure average is set as the input variable of the injector characteristic field. Conveniently, the rail pressure average is set to 800 bar according to the above-mentioned pressure range. If the B-side rail pressure sensor fails, then the rail pressure average is also set instead of the B-side actual rail pressure. In the case of a double fault, the energization duration is dependent on the desired injection quantity and the rail pressure average, independent of the Ignition sequence calculated. The advantage of this approach is that even after failure of one or both rail pressure sensors, the energization of the injectors can still be determined with sufficient accuracy.

- the internal combustion engine 1 is controlled via an electronic engine control unit 10 (ECU), which contains the usual components of a microcomputer system, For example, a microprocessor, I / O devices, buffers and memory devices (EEPROM, RAM) includes. In the memory modules relevant for the operation of the internal combustion engine 1 operating data in maps / curves are applied. About this calculates the electronic control unit 10 from the input variables, the output variables. In the figure 1 are as input variables of the electronic
- Engine control unit 10 exemplified an A-side rail pressure pCR (A), a B-side rail pressure pCR (B) and a size ON.

- Characteristic feature of the illustrated embodiment is the independent control of the A-side rail pressure pCR (A) of
- the A-side rail pressure control circuit 1 1A are: a target rail pressure pSL, a target consumption Wb, the engine speed nMOT, a signal RD (A), an emergency operation current value iNB, a PWM fundamental frequency fPWM and a magnitude E1.
- the size E1 summarizes the battery voltage and the ohmic resistance of the intake throttle coil with supply line, which are included in the calculation of the PWM signal.
- the output of the A-side rail pressure control loop 11A is the raw value of the A-side rail pressure pCR (A).
- the actual rail pressure plST (A) is calculated by means of a filter 12A. This is then with the target rail pressure pSL on a Summation point A, resulting in a control deviation ep (A) results.
- a pressure regulator 13A calculates its manipulated variable, which corresponds to a regulator volume flow VR (A) with the physical unit liters / minute.
- the calculated nominal consumption Wb is added to a summation point.
- the target consumption Wb is calculated as a function of a desired injection quantity and the engine speed (FIG. 3). The result of the addition corresponds to an unlimited A-side target volumetric flow VSLu (A), which has a
- Limit 14A is limited depending on the engine speed nMOT.
- Output of the limit 14A corresponds to a target volume flow VSL (A), which is the input of a pump characteristic 15A.
- An electric current iKL (A) is assigned to the setpoint volume flow VSL (A) via the pump characteristic curve 15A.
- the pump characteristic 15A is designed in such a way that a decreasing current iKL (A) is assigned to an increasing nominal volume flow VSL (A).
- the switch SR1 is in the position 1, so that the target current iSL (A) corresponds to the current iKL (A) calculated via the pump characteristic 15A.
- the target current iSL (A) is an input of the calculation PWM signal 16A.
- a PWM signal PWM (A) is calculated as a function of the desired current iSL (A), with which the solenoid of the A-side suction throttle is then activated. As a result, the path of the magnetic core is changed, whereby the flow of the A-side
- Suction choke normally open and is applied with increasing PWM value in the direction of the closed position.
- High pressure pump are summarized in unit 17A.
- the triggering of the A-side intake throttle can be subordinated to a current control loop 18A, in which the intake throttle flow iSD (A) is detected as a control variable, filtered via a filter 19A and fed back to the calculation 16A as the actual current ilST (A).
- High-pressure pump in the A-side rail generated A-side rail pressure pCR (A) is then detected via the A-side rail pressure sensor. This closes the A-side rail pressure control loop.
- the A-side rail pressure control loop is supplemented by a function block emergency operation 20A.
- Its input quantity is the A-side rail pressure pCR (A).
- the function block 20A includes the following functions: the monitoring of the A-side rail pressure sensor based on the A-side rail pressure pCR (A), the switching to the A-side emergency operation by setting the signal RD (A) and the output of a Not sunnysan Kunststoffsignals.
- the Not sunnysan tenusignal is in this case selected so that it reliably comes to an opening of the passive, here: A-side, pressure relief valve (Fig. 1: 9A).
- the emergency operation is set by the signal RD (A) is set in a first step and in a second step as Not sunnysan Tavernsignal the emergency operating current value iNB is output.
- the switch SR1 changes to position 2, so that now the target current iSL (A) corresponds to the emergency operating current value iNB. If the A-side intake throttle is controlled in negative logic as described above, then
- a PWM emergency operating value PWMNB can be used as the emergency operating drive signal
- PWMNB 0%
- switch SR1 would then be located within PWM calculation 16A.
- Another embodiment is that switching from the pump characteristic 15A to a limit curve. In this embodiment, the current iKL (A) calculated over the limit curve would then be the emergency operation drive signal. In FIG. 2, these variants are shown as dashed output variables of the functional block 20A.
- FIG. 3 shows in a block diagram the A-side rail pressure control loop 11A with emergency operation function, the B-side rail pressure control loop 11B with emergency operation function, a map 21 for setting a target rail pressure PSL, an injector map 22 for calculating the energization time BD, a calculation 23 for determining the setpoint Consumption Wb and the switches SR2 to SR7.
- the input quantities of the block diagram are the engine speed nMOT, a target torque TSL, the A-side actual rail pressure plST (A), the B-side actual rail pressure plST (B), the rail pressure average pM, the signals RD (A ) and RD (B), the ignition sequence ZF, a target emergency service pressure pNB (SL) and a target injection quantity QSL.
- the injection quantity QSL corresponds to the manipulated variable of the speed controller in a variable-speed internal combustion engine.
- the target injection quantity is derived from the power desired, for example, the accelerator pedal position.
- the output variables of the block diagram are the energization time BD of the injectors, the raw values pCR (A) of the A-side rail pressure and the raw values pCR (B) of the B-side rail pressure.
- the A-side target rail pressure pSL (A) and the B-side target rail pressure pSL (B) correspond to the target rail pressure pSL.
- the desired rail pressure pSL in turn is calculated via the map 21 as a function of the setpoint torque TSL and the engine speed nMOT.
- the switch SR7 is also in position 1. The pressure pINJ is therefore determined by the position of the switch SR4. If this is in position 1, the pressure pINJ is identical to the A-side actual rail pressure plST (A).
- the pressure pINJ is identical to the B-side actual rail pressure plST (B).
- the position of the switch SR4 changes as a function of the ignition sequence ZF. If an A-side injector to be controlled, the switch SR4 is in position 1, so that the
- Bestromungsdauer BD via the injector map 22 depending on the target injection quantity QSL and the A-side actual rail pressure plST (A) is calculated.
- the switchover takes place in such a way that, for the calculation of the energization duration BD via the injector map 22, that actual rail pressure which corresponds to the currently actuated injector is always used.
- A-side rail pressure sensor If now a defective A-side rail pressure sensor is detected, it is changed to the A-side emergency operation, in which the A-side rail pressure is controlled.
- A-side emergency operation as described for FIG. 2, the A-side rail pressure is successively increased until the response of the A-side pressure limiting valve.
- the B-side rail pressure continues to be regulated.
- the switch SR3 remains in the position 1, that is, the B-side target rail pressure pSL (B) is further identical to the target rail pressure pSL, which via the Map 21 is calculated. In this case, the B-side rail continues to operate at the optimum rail pressure, with the benefit of consistent emissions and high engine performance.
- a target emergency service pressure pNB 1500 bar
- the switch SR3 by setting the signal RD (FIG. A) changes to position 2.

- the illustrated example was based on that embodiment in which the setpoint of the intact rail is set to the desired emergency service rail pressure pNB (SL) when emergency operation is set. This is the second embodiment as described in FIG.
- This set point jump is followed by the B-side actual current ilST (B) with a time delay, the course of which results from the energy stored in the suction throttle coil. Since the suction throttle is completely opened without current, after the time t1, the B-side actual rail pressure plST (B) increases successively.
- FIG. 5 shows a first program flow chart for determining the pressure pINJ.
- the pressure pINJ is an input variable of the injector map (FIG. 3: 22) for determining the energization duration with which the injectors are driven.
- query result S1 yes, then it is checked at S9 whether the B-side rail pressure sensor is defective. If this is not the case, query result S9: no, then it is queried at S10 whether the next injection takes place on the A side. If this is not the case, that is, the next injection takes place on the B side, the pressure pINJ is set to the value of the B-side actual rail pressure plST (B) at S1 1. If, on the other hand, the next injection on the A side, query result S10: yes, then the pressure pINJ is set to the rail pressure average pM at S12, since the A-side rail pressure sensor is defective.
- FIG. 6 shows a second program flowchart.
- the A-side actual rail pressure plST (A) is calculated from the A-side raw values pCR (A).
- a query is made at S2 as to whether a defective B-side rail pressure sensor has been detected.
- Control deviation ep (A) calculated from the deviation from the A-side actual rail pressure plST (A) to the A-side set rail pressure pSL (A).
